“…For a given volume of 10, 000m 3 , four different tri-lobed models were developed based on the standard envelope profiles, viz., Ellipsoid, NPL, Zhiyuan, and Wang. Following the approach described in the methodology, added mass matrices were computed.…”

In recent years, there has been an increasing interest in the research and development of hybrid airships for various applications. Airship design involves multiple design parameters from various disciplines that interact mutually. Existing design methodologies, however, are often limited to fixed shapes and geometry. This paper provides a comprehensive parametric design approach for the sizing of multi-lobed hybrid air vehicles for low- and high-altitude applications. The proposed design techniques are robust so that the designer has the freedom to change the number of lobes, the relative location of lobes, the envelope profile, and the optimiser for the design optimisation process. The outcomes of the proposed methodology are envelope volume, wetted surface area, length and span of the envelope, sizing and layout of the solar array, and sizing and layout of the fins. The modeling techniques highlighted in this paper are very efficient for the design and optimisation of multi-lobed airships in the conceptual design phase with a large design exploration space. The robustness of the shape generation algorithms is tested on some of the standard envelope profiles of airships. The effect of the shape and geometry of the multi-lobed envelope on added mass is demonstrated through the added mass estimation using Boundary Element Method.

“…16 As a cargo aircraft for long-distance transportation, HAs have both size and economic advantages over the conventional airships 17 and for the industrial perspective, the simpler construction allows for the production of a significantly cheaper aircraft when compared to a jet airliner of similar capacity. 18 In addition, the efficiency improves dramatically with scale, 15 that is, larger vehicles are more efficient.…”

“…Haque et al, 45,46 considering the HAs of winged configuration, chose and optimize a suitable value of wing loading to satisfy full mission profile as with an aircraft design process. Agte et al 18 deduced a master constraint equation as often in wing airplane designs, to use the thrust-to-weight, the wing loading, and the volume to surface area ratio sizing the HAs. Although it is quite reasonable to design HAs using the analogy method, there are also, to author's knowledge, a few boundaries needed to be claimed.…”

An increasing focus on hybrid airships and the developments in renewable energies has allowed a methodology for conceptual design and analysis to be described. After a model presented and its aerodynamic characteristics obtained through a computational fluid dynamics method, two types of hybrid airships, solar powered at high altitudes and hydrogen powered for cargo, are demonstrated using a wing loading as their independent variable. Then the constraints determining the design point are presented. Parametric estimates of two types for component mass are then illustrated on distribution diagrams. And the sensitivity of wing loading and its effects on hybrid airships are discussed.
